binding with block does not work

[jazzbox@…]

$ cat y.rb 
class Foo
  def get_binding
    binding
  end
end

b = Foo.new.get_binding { "got it"}

p eval "block_given?", b
p eval "yield", b

$ macruby y.rb 
false
(eval):in `<main>': no block given (LocalJumpError)
	from core:in `eval:'
	from y.rb:in `<main>'

$ ruby y.rb 
true
"got it"

I added a failing test for test_vm/eval.rb

Thanks for the test case, I merged it and fixed the problem in r2819.
